The soluble form of the urokinase receptor, suPAR, has been suggested as a novel biomarker of low-grade inflammation. Activation of the immune system has been proposed to contribute to the development of depression and suicidal behavior. In order to identify depressed and suicidal individuals who could benefit from an anti-inflammatory treatment, a reliable biomarker of low-grade inflammation is v

In this review, we analyze several types of graphene-based sensors for glucose detection with respect to their preparation, properties and efficiency in electro-chemical processes. Graphene may display different types of defects, which play a role in the electron transfer processes. Oxygenated groups on the edges of graphene planes reduce the graphene in-plane conductivity, but may enhance the het

This paper presents an iterative decoder for faster-than-Nyquist (FTN) and orthogonal signaling multi-carrier systems. FTN signaling is a method of improving bandwidth efficiency at the expense of higher processing complexity in the transceiver. The decoder can switch between orthogonal and FTN signaling modes and exploits channel properties to improve bandwidth efficiency. The decoder is fabricat

OBJECTIVE - We assessed the association between A1C and cardiovascular diseases (CVDs) in an observational study of patients with type 1 diabetes followed for 5 years. RESEARCH DESIGN AND METHODS - A total of 7,454 patients were studied from the Swedish National Diabetes Register (aged 20-65 years, diabetes duration 1-35 years, followed from 2002 to 2007). RESULTS - Hazard ratios (HRs) for fatal/n

Background: High-dose chemotherapy (HDT) was added to conventional chemotherapy in Ewing sarcoma family tumor (EFT) patients, poor responders (PRs) to induction chemotherapy in order to improve their survival. Patients and methods: Patients aged

Popular Abstract in Swedish Bröstcancer är kvinnans vanligaste cancerform och globalt sett den cancer som leder till flest dödsfall. Bröstcancerscreening med mammografi används därför i syfte att hitta cancern tidigt. En tidigt upptäckt cancer har oftast en bättre prognos med möjlighet att minska dödligheten i bröstcancer. Mammografitekniken är dock behäftad med vissa begränsningar vad gäller känsAbstract: Mammography is currently the established method in breast cancer screening, although the sensitivity is known be affected by overlapping tissue concealing tumours. Breast tomosynthesis takes advantage of multiple exposures at different angles reducing the negative effect of obscuring tissue. The aim of this thesis was to investigate the use of tomosynthesis in breast imaging with a spec

Popular Abstract in Swedish Bröstcancer är den vanligaste cancerformen hos kvinnor i Sverige, men även män kan drabbas. Hos män är det dock en mycket ovanlig cancerform. I Sverige insjuknar cirka 40 män per år av bröstcancer jämfört med cirka 8000 kvinnor per år. Bröstcancer hos män och kvinnor är på många sätt lika. Till exempel är sjukdomstecknen desamma och visar sig oftast som en knöl eller knCancer is today a major healthcare problem worldwide. There are many forms of cancer, which is a genetic disease, believed to result from a multistep process with genetic and epigenetic changes accumulating over time. Breast cancer is one of the most common forms of cancer in women, while it is much more rare in men. Male breast cancer (MBC) exhibits both similarities and differences with female b

In comparison to other insects, like honeybees, bumblebees are very effective pollinators. Even though landing is a crucial part of pollination, little is known about how bumblebees orchestrate the final, critical moments of landing. Here, we use high-speed recordings to capture the fine details of the landing behaviour of free-flying bumblebees (Bombus terrestris), while landing on a flat platfor

ADHD is a common neurodevelopmental/neuropsychiatric disorder affecting about 5 percent of children. About 2-3 percent meet diagnostic criteria in adulthood as well. The core symptoms include inattention with or without hyperactivity/restlessness and impulsivity. The main cognitive deficit involves executive functions, probably related to a weak reward system. Symptoms will affect daily functionin

Several studies have shown the value of using proximity data to understand the social context of users. To simplify the use of social context in application development we have developed Proximates, a social context engine for mobile phones. It scans nearby Bluetooth peers to determine what devices are in proximity. We map Bluetooth MAC ids to user identities on existing social networks which then

This article gives a short presentation of my research on ethical aspects of nutritional genomics and its application for personalised nutrition.

Allergic contact dermatitis (ACD) is a common T cell mediated skin disease. Small reactive organic molecules called haptens induce ACD. Haptens are not recognized by themselves, but need to bond to endogenous proteins in the skin, and processed further into complete antigens. Antigen specific T cells then recognize the resulting antigen. Although the haptens are well known, the chemical reactions

This paper presents an environmental system study of the production of propionic acid in a biorefinery system based on agricultural by-products. Here, propionic acid is produced by fermentation of glycerol, a by-product from biodiesel production, as carbon source and potato juice, a by-product from starch production, as nitrogen source. Biomass-based propionic acid leads to a greenhouse gas reduct

Background: Xylose isomerase (XI) catalyses the isomerisation of xylose to xylulose in bacteria and some fungi. Currently, only a limited number of XI genes have been functionally expressed in Saccharomyces cerevisiae, the microorganism of choice for lignocellulosic ethanol production. The objective of the present study was to search for novel XI genes in the vastly diverse microbial habitat prese

Context. In 1992 we began a precision radial velocity survey for planets around solar-like stars with the Coude Echelle Spectrograph and the Long Camera (CES LC) at the 1.4m telescope in La Silla (Chile) resulting in the discovery of the planet iota Hor b. We have continued the survey with the upgraded CES Very Long Camera (VLC) and the HARPS spectrographs, both at the 3.6m telescope, until 2007.

The understanding of the state of dissolution of cellulose in a certain solvent is a critical step forward in the development of new efficient solvent systems for cellulose. Nevertheless, obtaining such information is not trivial. Recently, polarization transfer solid-state NMR (PTssNMR) was shown to be a very promising technique regarding an efficient and robust characterization of the solution s

Feathers are amongst the most complex epidermal structures known, and they have a well-documented evolutionary trajectory across non-avian dinosaurs and basal birds. Moreover, melanosome-like microbodies preserved in association with fossil plumage have been used to reconstruct original colour, behaviour and physiology. However, these putative ancient melanosomes might alternatively represent micr
